Growl iconIt’s time again to circumvent Apple’s Mail Plugin policy and update the GrowlMail Bundle with the correct identifier string. Otherwise, after updating, Mail will tell you it has disabled the GrowlMail plugin and will move the bundle to ~/Library/Mail/Bundles (disabled).

To amend this, follow these steps:

  1. Quit Mail
  2. Move the GrowlMail.mailbundle Folder back into ~/Library/Mail/Bundles
  3. Enter the following two commands into your Terminal:
    defaults write ~/Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "1C58722D-AFBD-464E-81BB-0E05C108BE06"
    defaults write ~/Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "9049EF7D-5873-4F54-A447-51D722009310"
  4. Start Mail and enjoy Growl notifications for new eMail again!

Apple Mail under OS X Leopard doesn’t support the GrowlMail Mailbundle which comes as an extra when installing the Growl notificaiton framework. Since I really missed that feature, that has been with me as long as I own a Mac, I searched around the WWW to find a solution.
Luckily there is a way:

  • Quit Apple Mail
  • Download the Growl .dmg from its website and install GrowlMail
  • Launch the Terminal
  • Enter the following two commands
    defaults write com.apple.mail EnableBundles -bool YES
    defaults write com.apple.mail BundleCompatibilityVersion -int 3
  • Start Apple Mail and enable the GrowlMail plugin
  • Be happy ever after 🙂
